Super-groovy and unique!  Maker's tag reads "Staggs of Great Britain", but I could find no info on this vintage brand. No other tags are present (i.e. materials or place of manufacture).

Single breasted, 2-button front (bottom button is missing). 1 button at each cuff end. Notched lapels, and 2-vent rear. Left front breast pocket, and 2 slanted waist pockets with flaps. 3 pockets in partially lined interior.

Outer material is not listed, but feels like fine cotton or perhaps silk. Lining appears to be acetate.

Good condition, with the only noticeable flaws to be that the lower of the front two buttons is missing, and one small spot near the shoulder seam, where there was slight fraying to the material, which was touched up with a dab of anti-fray fabric cement (see pencil tips in pictures).   Clean, nonsmoking home.  See all pictures for greater conditional detail.
